Product Overview
Periodic Certification (Inspection or Calibration grade) of test sieves is recommended as with any precision laboratory instruments. Generally, the finer woven wire cloth requires more frequent inspections. Re-Certification schedules greatly depend upon your media, frequency of usage, sieve handling and care, and your internal quality system requirements.
Certification Grade Levels:
-
200C – INSPECTION: Certificate contains inspection data from a percentage of apertures measured based on the ASTM E11 standards table providing a confidence level of 99.0% that each sieve is within the specifications.
-
300C – CALIBRATION: Certificate data contains at least twice as many apertures measured than “Inspection” grade sieves, thereby providing the highest confidence level available of 99.73%.
RE-CERTIFICATION SCHEUDLE:
Refer to the table below for the recommended schedule. Also below are instructions on how to submit your sieve for re-certification.
